PTFE Bushings
PTFE bushing or PTFE bushes are special mechanical vibration isolators made from polytetrafluoroethylene material. In the market, the PTFE bushings are also called Teflon bushing. However, Teflon is DuPont’s brand name for PTFE products.
The PTFE coefficient of friction varies between 0.05 and 0.10. Graphite-filled PFTE has a lower coefficient of friction. For this reason, polytetrafluoroethylene is a perfect material for oil-free PTFE bushes, making them the perfect substitute for metal bearing.
To improve the strength of the PTFE bush, it is important to add special fillers. Remember, virgin PTFE does not have superior mechanical properties. A reason carbon-filled PTFE bush bearing or glass-filled bushing are common is due to their improved mechanical characteristics.

Uses of PTFE Bush
You can use PTFE buses in applications that require reduces vibrations and noise. In most cases, you will find different PTFE busing sizes in shafts which are sliding, rotating, or linear motion.
Practical applications include;
- Conveyor systems
- Shafts in motion
- Drilling machines
- Gear systems
- Motor systems
- Systems with bearing systems
- Rotating wheels, etc.
